Kre-o Optimus Prime Papercraft Calendar

Can anyone tell me when this was originally released?

I intentionally brought some Kre-o today just so I could pick one up as a freebie (part of a Kre-o promotion in one of the stores here) and notice the copyright is 2011 so I'm assuming it's old?

The actual calendar part doesn't use year - just day and month which makes it functional regardless of how old it is. And it's Optimus... so I HAD to have it. ;)

It looks vaguely familiar from an old US news report on one of the American fansites, but it didn't get released here.
The date would be pretty accurate to the release year though.

The result looks pretty good.

Heh, I recently posted about the origins of modern papercraft toys. :)
